An electrical failure of the auto start/stop feature led to an unavoidable accident. I came to a stoplight, going slightly uphill, and the car shut off as designed. Releasing the brake re-engages the starter to continue driving, however when I released the brake, the carâs electrical system went haywire and the car immediately rolled BACKWARDS, damaging the car behind me. I took it to Subaru and the mechanic said the battery was low, but the car is designed NOT to initiate the start/stop feature, to prevent this from happening. They acknowledged that the accident was not my fault, but provided no further assistance. I was found at fault in the accident despite having no control over the scenario.
